There is one on the ground floor of Huadian Foreign Exchange Center across the road between Jiao A and the playground.
Take a bus from the back door to Meilianmei, where there is a super fitness.
The back door goes west (turn left) from the first intersection in the north of the city, next to Huilongguan Park, which is naturally bodybuilding. This environment is very good, so it is very expensive to have a swimming pool.
